b. 1923, Berkeley, California, USA. O’Flynn trained herself to try out drums as a little child, ultimately acquiring lessons while participating in school. Fighting with each other against the automated resistance towards ladies in jazz, specifically being a drummer, she ultimately joined up with an all-female music group led by Sally Banning. This is in 1939 and she afterwards played within an usually all-male music group co-led by Sally and George Banning. O’Flynn after that formed her very own all-male big music group, which she led before USA’s entrance into World Battle II. Following the battle, and by that point based in NY, she played in a variety of clubs, ultimately signing up for a trio led by Mary Lou Williams that also included June Rotenberg. In the middle-50s O’Flynn became steadily more discouraged using the entrenched behaviour that militated against her as a female in jazz, and in addition when racism affected the mixed-race rings with whom she occasionally proved helpful. Early in the next decade, she give up the business enterprise. In the first 80s, nevertheless, she reportedly informed Sally Placksin that she was lured to return. An excellent, supportive drummer with an excellent ear for all those she is associated, O’Flynn always chosen brushes, offering a discreet and simple rhythmic underpinning towards the bands where she worked.
